Let a = b
a X a = b X b ---------------------------- squaring on both sides...
a X a = a X b ---------------------------- since a=b
(a X a) - (b X b) = (a X b) - (b X b) --- subtracting (b X b) on both sides...
(a+b)(a-b) = b(a-b) ---------------------- since a2-b2=(a+b)-(a-b) and taking b common
a + b = b -------------------------------- canceling a-b on both sides
2b = b ----------------------------------- since a=b
2 = 1 ------------------------------------ canceling b on both sides.
So One = Two...
Undestood!!!!
How is it possible???
Where is the mistake...

I am absolutely no help when it comes to stuff like this. It about killed me in school trying to pass the tests with these types of problems. I just wanted to stop in and let you know that I read your post. Kudos to those that have the brain power to solve these problems.
